CLOSURE .MEANS FOR JARS:

Application filed- March'ii, 1924. Serial No. 69?,100.

To all to 7mm it may concern:

Be it" known that I; l/VALno EDWARD BRADEN, a subject of the King of Great Britain; residing at" Gidea; Park, in the county of Essex, England have invented new and useful Improvements in or Relatingto Closure'lvleans tor Jars of which the following is-a specification.

This invention relates to closure means for jars and more particularly for glass are havin-g'g lass lids provided with washers to ensure an air tightfit. Heretofore the wash ers-have been unattached to either the jar or lid and thereforeliableto be separated from thejar uponremoval of the lid.

According to=-the present invention the closure means comprises tongue members and springclipsretained in desired position.

by asuitablepositioning means, the tongues being adaptedto retainthe washer positivelyand' permanently in position on a seat ing surface whilst the spring clips-are so shaped thatupon the fitting of the lidthey move outwardly until i the lid or jar is broughtinto contactwvith the washer when theymove tov theiroriginal position, looking the lid and jar together.

In the accompanying drawingvarious modifications of my invention are illustrated.

Figure 1 shows one form .ofmy: invention having the spring clips aDCl tODgHBSLfOI gripping the washer attached to a metal ring;

Figure 2 is a Figure 1.

Figure 8 shows a modification wherein wire is substituted for the metal ring.

Figure 4 shows a form of the device for use with jars without a flanged mouth.

Figures 5 and 6 show a further modification in which the spring clips and tongues for gripping the washer are attached to the lid.

The lid 1 and jar 2 have inserted between them a washer of cork or the like 3 for ensuring an air tight fit. The washer is attached to the jar by tongues l which are united to or made integral with a ring 5 arranged circumferentially around the jar beneath the flanged mouth 6 thereof. The tongues 4 are of such length that they can be bent over the washer to secure it in position but do not extend the entire width thereof, thereby not interfering with the function of the said washer. Spring clip partial vertical section of members 7 are also attached to or madeinwiththe washer,; when they are sprung onto the lidbrim .to loelethe jar and lidHtogether. p i

As a modification, the ring arranged aroundithe jar can be replacedby wires 8,

the spring cli'ps andtongues in suohtarcase beingrintegral. The combined spring clip and tongue members 9 are held in position by the wireszS, one of which is retained against theiunderside oi' the flanged. mouth 6 of the jar by ridges ll arranged-in the-partsof the members 9 held between the *jar. and ,the wire. Any otherwiresSused are retained in their respective positions by like means.-

When the circumferential ringisof wire, the: wire maybe shaped tO fllllx also the tongues for securing; the washer in place and for forming the springclips, the wire in; such an instance" beingiessentially spring wire. Several strandsot thewirewmaybe combined. to give increased strength. i 7.

Inc the case of jars Without flanged months; the ring. 5lis prevented from rising and allowingtheuvasher to be loosenedaby an arrangement oi? retaining; bands- 12 which pass: longitudinally of-the jar and underneath thereof, and are securedto the ring 5Jat two lplaeesv Thesebands may be arrangedaas. r shown: in Figure 7 4, in i which case the ends of the bands 12 are continued beyond the ring 5, the continuations forming the tongues 4. They can however be so arranged that the continuations may act as the spring clips or one continuation may form the spring clip and the other continuation the tongue. Again the bands 12 may terminate at the ring 5, the spring clips and tongues being arranged at different places around the ring 5.

In the case of jars having flanged months the device can be arranged so that the spring clips, tongues and washer are carried by the lid. In such case, a ring 13 is arranged around the brim of the lid and retained in position by tongues 4: which are bent over the washer 3 for the purpose hereinbefore described. Spring clips 14 also attached to the ring 13 have inwardly projecting fingers 15 which cause the spring clips to be moved outwardly when the lid is being placed in position. These fingers fit against the underside of the flanged mouth 6 of the jar when the washer 3 makes contact with the jar, thus locking the jar and lid together. In the case of jars provided with a groove in place of the flanged mouth, the fingers on the spring clips can be suitably shaped to fit therein.
